Expose key Type-C port data in i915_display_info to make it easier to
understand the port configuration and active mode, especially whether
the link is in DP-Alt or TBT-Alt, without having to scan kernel logs.
Tested in DP-Alt, TBT-Alt, SST, and MST.
Expected output:
[CONNECTOR:290:DP-2]: status: connected
TC Port: E/TC#2 mode: tbt-alt pin assignment: - max lanes: 4
physical dimensions: 600x340mm
...
[CONNECTOR:263:DP-5]: status: connected
TC Port: G/TC#4 mode: dp-alt pin assignment: C max lanes: 4
physical dimensions: 610x350mm
v2: Use drm_printer (Ville)
Lock/Unlock around the printf (Imre)
v3: Forward Declaration drm_printer struct (Jani)
v4: Handle MST connector with no active encoder (Imre)
Add a delimiter between fields and ":" after the port name (Imre)
v5: Init dig_port and use it in intel_encorder_is_tc and tc_info (Imre)
Move tc->port_name to a newline (Imre)
v6: Use intel_tc_port_lock/Unlock (Imre)

Let's gradually start calling i915 and xe parent, or core, drivers from
display via function pointers passed at display probe.
Going forward, the struct intel_display_parent_interface is expected to
include const pointers to sub-structs by functionality, for example:
struct intel_display_rpm {
struct ref_tracker *(*get)(struct drm_device *drm);
/* ... */
};
struct intel_display_parent_interface {
/* ... */
const struct intel_display_rpm *rpm;
};
This is a baby step towards not building display as part of both i915
and xe drivers, but rather making it an independent driver interfacing
with the two.
v3: useless include additions dropped
v2: unrelated include removal dropped

Read PHY_VDR_0_CONFIG to check if there is any change in the register and
decide based on that if P2P sequence to change the data rate of LT PHY
are required or not. This scenario only happens if the requested mode
uses 1.62Gbps with DP mode since LT PHY defaults to this mode if
any other mode is requested we need to follow the whole sequence.

There is a hw restriction that we could enable the FBC for FP16
formats only if the pixel normalization block is enabled. Hence
enable the pixel normalizer block with normalzation factor as
1.0 for the supported FP16 formats to get the FBC enabled. Two
existing helper function definitions are moved up to avoid the
forward declarations as part of this patch as well.

The remaining utils display needs from i915_utils.h are primarily
MISSING_CASE() and fetch_and_zero(), with a couple of
i915_inject_probe_failure() uses.
To avoid excessive churn, add duplicates of MISSING_CASE() and
fetch_and_zero() to intel_display_utils.h, and switch display to use the
display utils.
As long as there are display files that include i915_drv.h, which
includes i915_utils.h, we'll need #ifndef guards for MISSING_CASE() and
fetch_and_zero() in both utils headers. We can remove them once display
no longer depends on i915_drv.h.
A couple of files in display still need i915_utils.h for
i915_inject_probe_failure(). Annotate this. They will be handled
separately.

Both sharpness and panel fitter use pipe scaler,
but only one can be enabled at a time. Furthermore
sharpness uses second scaler. So for CASF, check if

either of panel fitter or sharpness is enabled at
